ApplicatioufiledOctobei-2,1903. SerialNo-l75A97. (Nomodeh) To all whom,it may concern.-

check-controlled apparatus for the vending of.

fluids or other goods, and more particularly to that class of suchapparatus in which a coincheck serves as a connector between theoperating parts and the delivery mechanism.

The object of the invention is to improve and simplify the constructionand operation of machines of this character, and thereby render themmore eflicient and durable in use and less expensive to produce.

With this and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be more fully described, and pointed out in the appended claims.

In the accompanying drawings, Figure 1 is atop plan view of myimprovedcheck or coincontrolled apparatus adapted for operating afluid-delivery mechanism. Fig. 2 is a similar view with theoperating-lever and other parts omitted to more clearly illustrate theparts beneath them. Fig. 3 is a similar top plan view of the base-plateof the machine with the coincontrolled parts omitted to moreclearlyillustrate the fluid-delivery mechanism. Fig. 4 is a detailvertical sectional view taken on the line at m of Fig. 1 and showing thecoin way or passage. Fig. 5 is a top plan view, on an enlarged scale, ofthe operating-lever and the coin-controlled parts. Fig. 6 is an endelevation of the parts shown in Fig. 5 in an inverted position. x

Referring to the drawings more particularly, A denotes ahorizontally-disposed baseplate or other portion of a suitable frame orsupport upon which my improved coin-controlled apparatus is mounted.Said plate A is as hereinafter described.

formed adjacent to its center with an opening or slot a and at its rearwith a cut-away portion 6, adjacent to which'is secured a bracket 0.Beneath said plate A, as shown in Fig. 3, is mounted a fluid-deliveryvalve or faucet (Z, having a sliding valve-stem 21, which is opened byan outward or rearward sliding movement, as presently explained.Projecting vertically from the upper side of the plate A is a fixed studor pivot 2, upon which is pivoted a handlever 28, having at its outerend a hand-piece 28 and at its inner end a nose or projection 38. Saidlever 28 is held to the left in its normal position by a coil-spring 28,as shown in Fig. 5. Pivoted also upon said pivot pin or bolt 2*, butbelow and independent of the lever 28, is a coin-locking member 2 in theform of an irregular-shaped plate, as clearly seen in Figs. 5 and 6.Said swinging or oscillating member or plate 2 is formed upon its upperside with a raised or thickened portion 2", which is recessed to form anoverhanging portion 33 and a space 3 beneath the latter. The under sideof said member 2 is formed with a shoulder 27 and has a friction-roller2 journaled adjacent to one of its side edges. Said member 2 is held inits normal position, as shown in the several views of the drawings, by acoil-spring 11 and is only oscillated when it is locked or connected tothe hand-lever 28 by a coin or check, Pivoted at the rear of the upperside of the member or plate 2- upon a pin or screw 9 is a swinging arm9,

which is pressed normally against the portions 2 and 33 of the member 2by a coilspring 37. Said arm 9 is thus pivoted at one of its ends, andto its opposite end is pivoted, by means of a pin or rivet 1, a swingingcoinengaging member 1, as clearly seen in Fig. 5

of the drawings. Said member 1 has a portion 1 formed with a nose orprojection 39, which lies normally in the path of the nose 38 on thelever 28, so that when the latter is swung to the right the portion 1"of the member 1 will be swung into the space 3 beneath the overhangingportion 33 of the member or plate 2, in which portion 33 is formed avertically-disposed coin passage or way 4, as shown. The portion l ofthe member 1 lies normally under the outer edge of the portion shown inFig. 4.

33, as seen in Fig. 5, but does not cover the coinway 1. Said member 1is also formed at its rear end with a projection 34:, which is connectedto a similar projection 35 on the arm 9 by a coil-spring 36, whichserves to hold said member in its normal position. Fixed upon the underside of the arm 9 is adepending pin or stud 5, which projects through acurved or cam slot 6, formed in the rear edge of the member or plate 2,and also through a similar slot 10, formed in the free end of a curvedplate 10, pivoted at 10" upon the under side of the member or plate 2,as indicated by the dotted lines in Fig. 2, and serving as a bottom forthe coin way or passage 4 to limit the downward movement of a coin orcheck 14, as The lower end of said pin 5 contacts with a curved orcam-shaped ledge 18, formed upon the upper face of a plate 17, which ispivoted at one of its ends, as at 16, upon the upper side of thebase-plate A and which has its oppositeiend disposed beneath the rear orfree end of the bottom plate 10,'as seen in Fig. 2. Upon the upper sideor face of the rear or free end of said plate 17 are anupwardly-projecting lug 20 and a frictionroller 20, which lug and rollerare engaged by an arm 7, secured to a shaft 8, which is journaled in thesaid bracket 0 upon the baseplate A. Upon said shaft 8 is a second arm15, having a forked outer end 15, which ongages and operates the stein21 of the valve or faucet (Z. Also secured upon said shaft 8 is an armor lever 22, the forward or free end 22 of which is engaged by a catcherdetent 26, pivoted at 26 in a bracket secured to the base-plate A andactuated by a spring 26",-as shown. The arm or lever 22 and also thearms 7 and 15, which are secured to the shaft 8, are actuated by acoil-spring 32, which has one of its ends attached to'a stud 22 upon thelever 22 and its other end secured to asimilar stud 2 upon the port-ion33 of the member or plate 2, so that the tendency of the spring 32 is tomove the arm 22 inwardly and hold it in contact with the detent 26 orthe frictionroller 2 and also to move the arms 7 and 15 rearwardly oroutwardly, thereby opening the valve (1 and swinging the plate 17rearwardly to cause its cam-ledge 18 to actuate the pin 5, the movementof which will swing the bottom plate 10 from beneath the coinway 4 topermit the coin 1 1 to drop through the slot a in plate A and fall intoa suitable coinbcx. (Not shown.) One end of the detent or dog 26, aspreviously stated, engages the end 22 of the arm or lever 22, and itsopposite end 26 lies in the path of the said shoulder 27, which isprovided upon the under side of the member 2 and is adapted to actuatesaid detent to disengage it from the arm or lever 22.

The operation of the invention is as follows: When a check or coin 1 1is deposited in the coin-passage 4, it falls upon the plate 10, as seenin Fig. 4. and blocks the space 3 in '39 and move the member 1 intoengagement with the coin, which will thus serve as aconnector and causethe coin-locking member 2 to oseillatewith the lever 28 against thetension of the spring 11. As the member 2 is thus oscillated itsshoulder 27 will engage the detent 26 and cause it to disengage the armor lever 22. The spring 32 will then swing the arm 22 inwardly until itcontacts with the roller2, and the movement of the arm 22 will, throughthe shaft 8, swing the arms7 and 15 rearwardly. The rearwardmovement ofthe arm 15 will actuate the valve-stem 21 to open the valve d and permitof the discharge of a certain quantity of fluid, and the arm 7 'in itsrearward movement will engage the stud 20 and roller 20 and cause theplate 17 to be swung rearwardly. In this movement of the plate 17 thepin 5 will ride over the cam-ledge 18 and be moved rearwardly to bothswing the bottom plate 10 rearwardly to release the coin 1 1 and toswing the arm 9, and hence the member 1, rearwardly to permit the nose38 of the lever to pass the nose 39 on said member 1. As soon asreleased the lever 28 and also the member 2 will return to their normalpositions by reason of their springs 28" and 11, and the return movementof the member 2 will force the arm 22 to its original position, in whichit will be locked by the detent 26. The arms 7 and 15 and springs 36 and37 willrestore the other parts of the apparatus to their normalpositions, as will be readily understood. If the hand-lever 28 should beturned without previously depositing a coin in the coinway 1, it will beseen that portion 1 of the coin-engaging member 1 will be swung into thespace 3 without ac- 'tuating the member 2. WV hen the nose 38 passes thenose 39, the spring'36 will restore the member 1 to its normal position,and the nose 38 in the return movement of the lever 28 will be permittedto pass the nose 39, owing to the manner in which the member 1 ismounted.

While 1 have shown anddescribed the preferred embodiment of myinvention, 1 wish it understood that I do not limit myself to theprecise construction herein set forth, since various changes in theform, proportion, and the minor details of construction may be resortedto without departing from the principle or sacrificing any of theadvantages of this invention.

It will be further understood that the coincontrolled mechanism may beused for vend- 1 the construction and operation of the invention will bereadily understood without requiring amore extended explanation.
